Holmium Oxide Test
Holmium Oxide Test
The holmium oxide test uses three characteristic absorbance maxima of the
built-in holmium oxide filter to verify wavelength accuracy (see also
“Wavelength Verification and Recalibration” on page 183). When the test is
started, the 1-nm slit is moved into the light path automatically. To eliminate
effects due to absorbing solvents, the test should be done with water in the
flow cell.

Limits:
The test is evaluated by the instrument, and the measured maxima are
displayed automatically. The test fails if one or more of the maxima lies
outside of the limits (see Figure 68 on page 175).
